Holding three chips (two 74s, one 72) Noise MK's S&H not strictly a noise and envelope generator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md) How to use 7.5mm holes, not 6mm - alpha pots - 9.8mm, +2mm - rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm? Alpha pots: tight, only 1/2 turn for nut 11mm - rotary, SR2511 style, with very large 17.5mm panel hole+snip off pin, add holes for easier printing

Fix pots going the wrong side of D35, but other options exist. Single-step button (SW13) isn't producing a high enough voltage to another voltage. Useful here for pitching up from a base.
